The invention is a three stage wastewater treatment system having a first tank, a second tank and a third tank, all in fluid communication and forming a unitary structure. The first and second tanks are nested, where the first tank is the innermost tank. The first tank has a clarifier structure disposed therein separating the interior of the first tank into a quiescent zone and an aeration zone. Positioned in the aeration zone is at least one air injector positioned. The treatment system is covered, and is generally buried (but can be used above ground).

Unitary three stage wastewater treatment system

An wastewater treatment system is provided. The system includes a cylindrical tank having a sidewall, a bottom, an upper portion and a lower portion. A cone-shaped hopper, open at both ends, is positioned in the tank. The hopper's upper opening is larger than the lower opening. The system includes a compressed air source connected to at least five radially spaced air outlet pipes, each air outlet pipe being fluidly connected to the compressed air source and extending downward into the lower portion of the tank and having an open end positioned above the bottom between the hopper and the sidewall of the tank so as to discharge air into an aeration zone between the hopper and the tank sidewall; an inlet line connected to the tank and having a discharge end opening into the tank between the hopper and the tank sides; and an outlet line having an inlet end positioned within the hopper in the upper portion of the tank and an outlet end exterior of the tank, whereby the wastewater within the tank is continuously aerated through the air outlet pipes with a sufficient volume of air and sufficiently large bubbles such that the wastewater is continuously agitated within the tank exterior of the hopper so as to eliminate any quiescent zones in the upper portion of the tank.

Apparatus for treating wastewater

An apparatus and method for treating wastewater is provided including a cylindrical tank having a top, a bottom, an outer wall and a cylindrical inner wall. The inner wall extends from the bottom of the tank to a point above a desired water level. The inner wall, the top and the bottom define an inner aerobic zone. The inner wall, the outer wall, the top and the bottom define an outer anaerobic zone. Wastewater may pass from the outer anaerobic zone to the inner aerobic zone through holes in the inner wall. An open ended conical hopper is positioned within the inner aerobic zone with its smaller end pointed toward the bottom of the tank. Several radially spaced air outlet pipes connected to a compressed air source extend downward into the inner aerobic zone where air is discharged through the open ends of the outlet pipes. An inlet line connected to the tank opens into the outer anaerobic zone of the tank. An outlet line is positioned within the clarification zone to remove purified water from the tank. Wastewater is treated by anaerobic bacteria in the outer anaerobic zone and by aerobic bacteria in the inner aerobic zone. Aerobic bacteria, forced through holes in the inner wall by aeration occurring in the inner aerobic zone, denitrify the wastewater as they are starved of oxygen in the outer anaerobic zone. Finally, suspended solids settle out of solution in the clarification zone prior to the purified water leaving the tank.

Apparatus and method for treating wastewater

In a waste water treatment system having a container and waste water disposed therein, an apparatus for treating a sludge blanket comprising at least one spray assembly, the spray assembly fluidly connected to a source of fluid, the spray assembly having a spray head positioned above the waste water, the spray head being adapted to spray fluid such that when fluid is sprayed from the spray head, the sprayed fluid will suppress a sludge blanket on the waste water.

Spray sludge suppression system

An apparatus and method for treating wastewater is provided including a cylindrical tank having a sidewall, a bottom, an upper portion and a lower portion; a hopper positioned within the tank, the hopper having sides, an upper opening located in the upper portion at a point above a desired water level within the tank and a lower opening located in the lower portion of the tank, the hopper sides diverging from the lower opening to the upper opening, the lower opening being smaller than the upper opening; a compressed air source; at least five radially spaced air outlet pipes, each air outlet pipe being fluidly connected to the compressed air source and extending downward into the lower portion of the tank and having an open end positioned above the bottom between the hopper and the sidewall of the tank so as to discharge air into an aeration zone between the hopper and the tank sidewall; an inlet line connected to the tank and having a discharge end opening into the tank between the hopper and the tank sides; and an outlet line having an inlet end positioned within the hopper in the upper portion of the tank and an outlet end exterior of the tank, whereby the wastewater within the tank is continuously aerated through the air outlet pipes with a sufficient volume of air and sufficiently large bubbles such that the wastewater is continuously agitated within the tank exterior of the hopper so as to eliminate any quiescent zones in the upper portion of the tank.
